Now, using your code from Chapter $7$ Case Study $1,$ modify your program so every data entry statement uses a TryParse$()$ method to ensure that each piece of data is the correct type.

I used the code below and still failed the test for Task #$01$: All data entry statements use a TryParse$()$ method. I was wondering if someone could make sure TryParse$()$ method is in every place it should be$.$
